Brilliant ultra-wide lens at a very reasonable price,
Verified Purchase(What is this?)
This review is from: Canon 9519B005AA EF-S 10-18mm f/4.5-5.6 IS STM Lens (Camera)
This is a terrific lens at a price that's very reasonable for the level of performance you get. TL;DR version - buy it, it doesn't disappoint.
If you're still reading, I've been wanting to try ultra-wide fields of view, but while i've been um'ing and ah'ing about the Canon 10-22mm for at least a year I couldn't really justify the cost for what will be a fairly infrequently used lens for me. When the 10-18mm appeared on Amazon UK at just under half the price of the 10-22mm it made the decision very easy. Although it's early days i've given it decent workouts in full daylight, sunrise/sunset, and inside buildings, and results are consistently excellent for the price - sharp, a little barrel distortion at 10mm but not bad (I quite like the effect it gives) and 12-18mm are very good. Great results with wide-angle HDR sunsets.
As noted in another review it's fairly slow at f/4.5-5.6, but i've not found this a major issue - the IS seems effective when handheld, but I mostly shoot tripod-mounted anyway. With my 600D in low light I get better results from manual settings than auto/landscape which seems to go a bit underexposed, but that's a minor criticism of the camera rather than this lens. Focus is snap-to, quick and quiet, i've not encountered any issues there at all. The lens is plastic and very similar in construction to some of the kit lenses; as a result it doesn't really have the solid feel of Canon's more expensive lenses but is nevertheless well made, plus the construction makes it small and very light, which is a definite positive - makes it easy to stash away in the camera bag on a walkabout when you might well leave a heavier lens behind. Given that i'm unlikely to be in a situation where this is the only lens I'd want to have with me, overall i'd say the lightweight construction is a bonus rather than the negative that a few reviews elsewhere see it as.
